A language over an alphabet is regular iff it can be accepted by a finite automaton. The best way to prove this theorem is to visualize a finite automaton as a directed graph (its state diagram ). We prove sufficiency and necessity separately. Lemma 1.

WebMar 2, 2024 · $\begingroup$ I think it's fairly easy to explain with an example: If I've written a Python program and saved it as myscript.py, and I want to run it on input mydata.txt, I issue the command python myscript.py mydata.txt on the command line. From the operating system's perspective, the only program is python, and the other two arguments are just … WebThe statement and proof of Theorem 3.5 are given with little explanation at the end of §2 of Kleene (1938, 153).

In computability theory, Kleene's recursion theorems are a pair of fundamental results about the application of computable functions to their own descriptions. The theorems were first proved by Stephen Kleene in 1938 and appear in his 1952 book Introduction to Metamathematics.
